Apple Desktop Bus (ADB) Optical Mouse Retro Board

Optical Sensor Retrofit Replacement Board for Classic Apple Wedge ADB Mouse

This listing offers a replacement board to stealthily update your classic Apple ADB wedge ball mouse with an optical sensor. It uses the original ADB port which was introduced with the Apple IIGS, Macintosh SE and Macintosh II and was used until the late 1990s. If your mouse has lost its ball or it has stopped working, this board will help get it working again.
